I did a lot of tests, and I finalized my research. Paper has become a part of my visual vocabulary. You know, paper is an industrial material. You can do almost anything with it. Wood, for example, is much more difficult to adapt to different needs.

I travel a lot. Japanese culture is very ancient and very strong. That's why most people who commission work from Japanese architects expect them to create works that have an element of exoticism, the kind typical of Japanese culture. I don't do that.

Architecture is not about designing somehting from a free, fanciful idea. It is about discovering and establishing one's own principle, some kind of regularity - finding an individual formula to apply to one's buildings.

Architects mostly work for privileged people, people who have money and power. Power and money are invisible, so people hire us to visualize their power and money by making monumental architecture. I love to make monuments, too, but I thought perhaps we can use our experience and knowledge more for the general public, even for those who have lost their houses in natural disasters.

For me, there's no difference between what's temporary and what's definitive. I built the church in Kobe, which was supposed to be temporary, and people liked it so much that there's a version of it still there today - unlike some concrete buildings that were just built for money and that can be destroyed from one day to the next. Concrete can be very fragile during earthquakes.

I believe that the material doesn’t need to be strong to be used to build a strong structure. The strength of the structure has nothing to do with the strength of the material.

Everyone used to want to be star architects. That's no longer the case.
